RAIL JOINT. 1 i

Application Ilediiarch 16, 1922. Serial No. 544,118.

To @ZZ fic/710m if may concern.'

Be it known that l, HARRY i. STRAINING, a citizen of the United States, residing at Knoxville, in the county oi Knox and State ot Tennessee, have invented a new and useiul improvement in Rail Joints, ot which theV following is a specitication, reference being had to'the accompanying drawing.

My improvement relates particularly to railway rail joint structures wherein provision is made 'for holding nuts on the rail joint bolts against turning movement after the nuts have been set.

The object ot the invention is to provide such a structure comprising parts which are easilyassembled and effective aite'r they have been assembled. ln my improved structure, the members which engage the nuts are to be applied after lthe bolts and nuts have been applied and set. l

in the accompanying drawings,

Fig. l is a side elevation of a joint formed at the meeting ends of two rails and embodying my structure;

Fig. 2 is a plan of the same structure, the right hand part being sectioned horizontally on the line, 2-2, of Fig. l;

Fig. 3 is an upright section on the line, 3 3, of Fig. 2, looking toward the right;

Fig. 4 is a section on the line, i-FLL, of Fig. 3, looking toward the lett;

Fig. 5 is a plan oit one oi the bolts;

Fig. 6 is a perspective of one of the locking plates;

Fig. 7 is a transverse section on the line, T-J?, of Fig. 5, looking toward the right.

Referring to said drawings, A, A, are ordinary track rails having a toot, A1, a web, A2, and a head, A3. These rails meet end-to-end in the usual manner.

Fish plates, B, rest against the opposite sides or' the rails and extend across the joint in the usual manner. The upper edge of each fish plate bears against the lower 'face of the adjacent part of the head, r 3, and the lower part oi' such plate engages the toot, A1. Each plate has .tour horizontal, transverse apertures, B1, to receive the bolts. Each rail has apertures, A1, in alignment with the apertures, B1, of the fish plates.

The fish-plates are joined to the rails by means of bolts, a cylindrical shaft, C1, which is screwthreaded at one end. On the other end is a head, C2, which, in the form shown, is cylindrical.. At the side of said head todv C. Each bolt, C, comprises ward the threaded end is an elliptical orr the head opposite the enlargement, C3, isa horizontal extension, C4, which has a trans` verse aperture, C5, adapted to receive a cotter or cross pin or similar retaining member, CG. The nut, C7, is applied to the threaded end of the bolt and is turned until it bears against the adjacent fish plate and the head oi the same bolt is drawn against the outer face of the opposite fish plate, the nut being drawn as tightly as is required for good service, the turning stopping when the nut is in position to receive the jaws of one of the locking plates described below.

The two bolts at the same side of the joint are alternated in direction, so that a' bolt head and a nut will be on the outer tace of each fish plate lat each side of the meeting` ends of the rails.

After the bolts have been put into position and the nuts have been securely tightened to the desired extent, four locking plates, D, are applied. Each plate has at one end a horizontal, transverse aperture, D1, and jaws, D2, at the other end. The locking plate is moved horizontally toward the fish plate, the plate being so held as to cause the bolt extension, C, to enter and extend through the aperture, D1, while the adjacent nut, C1, extends between the jaws, D2. After the plate has been put into: that position, a cotter or cross pin, C6, is extended through the cotter aperture, C5. Said aper ture is preferably elongated in the direction of the length oit' the bolt, in order to adapt it to receive a broadened cross pin which will force the locking plate, D, against the head, C2. of the bolt. As shown in Figs. 2 and G, the locking plate has an oii'set, D3, which permits the end having-the jaws-to bear flatwise against the fish plate while the end having the aperture, D1, bears latwise against the bolt head, C2. y

When the parts have been thus assembled, the structure is complete, and all the nuts are held against turning.

It is to be emphasized, that by the use of the extension,- C1, of the bolt, each bolt Gah hnht iat@ notitioh and .ita-1 hat applied Without' inferencia, "te the ,.,llocking platt; that lthe locking plate is not tobe engaged or held by an@ at he halts WhiteA thabelta apa being applied""o`"1"iseci1eilj that@n on the" contrary, the bolts and nuts are to be ully placed and secured before the locking pl't'ts' are Placed', and that .loshihg nlattal are put into position Without disturbingnthe -maht "vtha'aut, substantially as destribed- '2- A'sartcles'ofmanufacture 01: use in forming railway miljoints, a bolt 'comprist, Stem, threaded it one end engl having ai. head' the other end and' having alt the side ,of the Vhead toward the; `thneucled end* a non-circular ehlahgemahtjahd having at the .when side et the head an externsahftrmed ing plate inflated @t Qa@ @het t0 hhtava Sad extension `and, formed aftjthe other end to anni@ 'uit .ai mate eagagenett with. a ma, substnntially as described.
